Protect any expensive or important appliances within your home using a surge protector. This can often allow you to identify and remedy the cause of the power surges, while ensuring that no damage can be caused to other appliances.
Identify which appliance is the source of the power surges by switching each one on and checking for a surge. Ensure power outlets are not overloaded, and that each large appliance is plugged into its own power outlet.
If one appliance causes a surge, arrange for an electrician to check your appliance and carry out any rewiring necessary. A qualified electrician will be able to replace your circuit breaker or fuse box if it is not sufficient to cope with your home's power needs.
If no single appliance seems to be the cause, switch on more than one at the same time. Choose appliances that are close together in the home as these are most likely to be on the same circuit breaker or fuse. If two appliances being switched on simultaneously cause a surge, plug them into different power outlets.
If you are unable to solve the problem, consult an electrician to examine and troubleshoot the electrical circuits in your home.
